Study on code theory and sequence design by copy theory

This paper introduces copy theory and researches its application in coding and the design of spread spectrum sequence. Firstly, copy theory is introduced in the second part. In the third part, we design a new algorithm to make OVSF code by Copy theory, and explain the OVSF code in theory. That is, OVSF code can be made by copy method, according to change of the copy information. In the fourth part, we design a novel algorithm to generate m-sequence in without knowing about primitive polynomial.
